Filter by:Cannabis use during adolescence represents a significant risk factor for the development of psychosis including schizophrenia. Moreover, cannabis is the most commonly used drug among patients with an existing psychotic disorder. An estimated 25% of patients with psychosis reportedly meet the criteria of a cannabis use disorder particularly among younger patients experiencing their first episode. Cannabis use significantly exacerbates symptomatology resulting in an increased duration of the first hospitalization visit, number of hospital readmissions, and overall reduced functional outcome. Discovering novel strategies to treat the underlying pathophysiology of cannabis dependence early in the disorder may translate into improved functional outcome. Working memory deficits have been shown to predict relapse in the first-year of psychosis and is modulated with cannabis use. Repetitive transcranial magnetic stimulation (rTMS) targeted to the dorsolateral prefrontal cortex (DLPFC) has shown tremendous promise for the treatment of both tobacco dependence and working memory impairment in patients with psychosis possibly through the modulation of gamma (30-50 Hz) oscillations. The proposed study will therefore evaluate the effect of rTMS on abstinence, working memory performance, and gamma oscillations through a randomized, double-blind, placebo-controlled 28-day longitudinal abstinence study design in patients with early psychosis. It will further explore if baseline performance and gamma oscillations predict abstinence in response to rTMS. It is hypothesized that active compared to sham rTMS will improve abstinence rates and improve working memory performance through the modulation of gamma oscillations.
A ten-week study to assess MP-101 in Dementia-Related Psychosis and/or Agitation and Aggression
This study will assess the efficacy of brief mindfulness practices on improving mental health in adults who are currently in treatment for mental health concerns. From online instructional videos, each participant will learn a thirty-second or three-minute mindfulness practice that is to be performed at least three times daily over two weeks.
Treatment with prednisolone can be used as a proof of concept to investigate the possibility of immune modulation as a treatment for schizophrenia. It is expected that daily treatment with prednisolone in addition to antipsychotic treatment reduces psychotic symptoms and improves cognition, as compared to placebo. The investigators propose to investigate the effects of administering the corticosteroid prednisolone versus placebo in addition to standard antipsychotic medication in patients with early stage schizophrenia or related disorders, hypothesizing that a decrease in the overall low-grade cerebral inflammation due to prednisolon treatment will be expressed as a decrease in overall symptom severity., Secondly, addition of prednisolone is hypothesised to slow down cognitive deterioration in recent-onset psychosis patients. Finally, the investigators aim to determine whether indirect immunological parameters of the hypothesised low grade inflammation status in schizophrenia are shifted due to the addition of prednisolone.
This study seeks to evaluate the long-term safety and effectiveness of nelotanserin for the treatment of visual hallucinations (VHs) and Rapid Eye Movement (REM) Sleep Behavior Disorder (RBD) in subjects with Lewy body dementia (LBD).
Reducing Duration of Untreated Psychosis (DUP) is a primary goal for improving long-term outcomes in young people with a first episode of psychosis (FEP). The "standard of FEP care" within the US focuses on targeted provider education regarding signs and symptoms of early psychosis to motivate patient referrals to FEP services, followed by initiation of services within largely clinic-based settings Experience at the Early Diagnosis and Preventive Treatment (EDAPT) FEP specialty program at U.C. Davis in Sacramento has identified two important bottlenecks to reducing DUP, consistent with reports in the literature from other FEP clinics. These are 1) delays in the identification of psychotic symptoms by referral sources, and 2) delays or disruptions of patient engagement in specialty FEP care. Building upon a comprehensive and established referral network of 20 sites across the Sacramento area (schools/universities, ER/inpatient hospitals, outpatient mental health, primary care), the investigators will address delays in patient identification and engagement using a two-phase, cluster randomized design. The investigators will consecutively test the impact of two interventions to reduce DUP, defined in this RFA as time from first onset of psychotic symptoms to engagement in FEP specialty care. To address identification delays, the investigators will examine the use of standard targeted provider education plus novel technology-enhanced screening compared to standard targeted provider education alone, testing the hypothesis that the education plus technology-enhanced screening will identify more patients, earlier in their illness. To address engagement delays, the investigators will compare the use of a mobile community-based, telepsychiatry-enhanced engagement team to standard clinic-based procedures for intake, engagement and initiation of treatment, to test the hypothesis that the mobile approach facilitates earlier and more stable engagement, thereby reducing DUP. The proposed work will provide new specific evidence-based practices for reducing DUP and improving outcomes through specialty care of individuals with a first episode of psychosis.
The purpose of the study is to characterize the effects of a single, sub-anesthetic dose of ketamine in rs-fMRI in healthy subjects. Post-ketamine rs-fMRI data will demonstrate a pattern of increased global brain connectivity (GBC) in fronto-temporal cortex.
Transcranial direct current stimulation (tDCS) is an investigational device that has not been approved for the treatment of any medical condition by the FDA but is allowed to be used for research purposes. In clinical trials tDCS has been associated with pain relief by decreasing the intensity and duration of chronic pain. tDCS potentially works by stimulating the brain by delivering an extremely low-level electrical current to areas below the forehead - areas associated with chronic pain. It is anticipated that this current will increase brain activity or the likelihood of brain activity in these areas, affecting individual's ability to regulate pain. The purpose of this study is to compare eligible participants in the Pain Management Program at The Menninger Clinic receiving adjunctive real transcranial Direct Current Stimulation (tDCS) versus those receiving sham tDCS in the resolution of chronic pain. The primary objectives are: (1) improving pain tolerance and (2) improving subjective pain experience. Secondary objectives are: (1) improving subjective experience of sleep quality and (2) increasing physical activity.
Background: People with psychosis show profound deficits in memory. A new cognitive remediation therapy using an app on a computer or mobile phone to improve memory has been effective in this population, but the neurobiological effects are unknown. Objectives: 1) To use functional magnetic resonance imaging (fMRI) to examine brain changes during a working memory task before and after a 12 hour memory training intervention on a computer or mobile phone, 2) To use diffusion tensor imaging (DTI) to examine white matter connecting prefrontal and parietal lobe before and after training. Methods: 46 people with psychosis will be randomized to a computerized training of either memory training or a control condition of non-memory games (language/card games) and will self-administer 4 hours of training over 4 days per week, for 3 weeks (12 hours total). Memory training will be done with the Peak app http://www.peak.net. Imaging data will be gathered with a 3 Tesla scanner pre and post training.
The primary aim of the project is to test the effectiveness of a cognitive remediation treatment (CRT) program, My Brain Solutions (MBS), in addition to motivational interviewing (MI) in improving cognition and functional outcome of individuals at risk of SMI. An active control treatment consisting of CRT alone will be used. Hypotheses: 1. Both study groups will have improvement in cognition at the end of treatment; 2. CRT+MI group will have increased treatment adherence and superior improvements in cognition at the end of treatment and 12 months post baseline compared to the CRT only group; Secondary Hypothesis: 3. Improved cognition will be associated with improved functional outcome.
